FREQUENTLY ASKED QUESTIONS
Yes, Nordost cables are directional. This is especially true for single ended (RCA) interconnects as the shield is connected at the source or output end only.
The directional arrows always point away from the source. For example, from a CD player to an amplifier, the arrows should point towards the preamplifier or power amplifier. On a speaker cable the arrows would always point towards the loudspeaker
When cables are manufactured they do not have any directionality. However, as they break in, they acquire directionality.
Although the cable signal is an alternating current, small impurities in the conductor act as diodes allowing signal flow to be better in one direction over time. This effect is also called quantum tunneling, which has been observed in experiments over 25 years ago. Regardless of the purity of the metal used, there are still diode effects in all conductors. In addition, the insulation material will change when it is subjected to an electrical field.
